Back when Google was doing it's beta test program for Chrome Netbook, I applied and luckily received my own free CR48 laptop.

I have used Chrome OS for a while and while it's pretty good if you just always want to use chrome browser I was feeling a bit lonely without root access and gnome desktop. So I manned (nerded) up and flashed CR48 BIOS to allow running unsigned code and installed Backtrack 5 on it. Now CR48 is infinitely more usable and entertaining. All hardware (except 3g modem, I haven't gotten around to using that yet) works fine, and I didn't have to install any drivers manually. Only thing I had to do is create a non root user for use for desktop type tasks because by default Backtrack only has root user.
